Thread: BUG #5960: No rule to make target 'libpq.a', needed by 'all-static-lib'

The following bug has been logged online:

Bug reference:      5960
Logged by:          Julia Jacobson
Email address:      julia.jacobson@arcor.de
PostgreSQL version: 8.4.6
Operating system:   Windows 7 with Msys/MinGW
Description:        No rule to make target 'libpq.a', needed by
'all-static-lib'
Details:

Dear PostgreSQL developers,

When trying to compile PostgreSQL 8.4.6 on Windows 7 using MSys (MinGW) in
order to build a static version of libpq by the commands
./configure --without-zlib --disable-shared
make
the compilation process ends with the error message
"No rule to make target 'libpq.a', needed by 'all-static-lib'".
This issue was already discussed here on the mailing list more than 6 years
ago and successfully fixed with a patch:
http://archives.postgresql.org/pgsql-hackers-win32/2004-10/msg00057.php
However, it seems to me like there is a similar problem in version 8.4.x.
Please corrected me if I'm wrong.

Regards,
Julia

hm, out of the blue, i believe you may have hitten yourself in the foot
with the --disable-shared option. If that fails. then maybe you'll have
different
results with postgresql 8.4.7..

Hello Etienne,

Thanks for your answer.
What do you mean by "you may have hitten yourself in the foot with the --disable-shared option"?
When I don't use this option, everything works fine.
Compiling PostgreSQL 8.4.7 doesn't work either.
The problem is that I need a static libpq. Leaving out the --disable-shared option doesn't results in some
pseudo-staticlibpq and my application still requires a dynamic libpq apart from the static one. 

Regards,
Julia

Well, the "--enable-static=libpq" option isn't very effective, since it
results in the following message:
configure: WARNING: option ignored: --enable-static
Therefore, I would be happy about the compilation with the
--disable-shared option finishing without errors.

I tried this on MacOS X and got a different error:

make -C interfaces all
make -C libpq all
make[3]: *** No rule to make target `libpq.5.4.dylib', needed by
`all-shared-lib'.  Stop.
make[2]: *** [all-libpq-recurse] Error 2
make[1]: *** [all-interfaces-recurse] Error 2
make: *** [all-src-recurse] Error 2

I also tried it on Linux (Fedora 12), where it completed successfully.

Unfortunately, I don't think we have any buildfarm coverage of
--disable-shared, so there is no automatic way for us to notice when
this has gotten broken.

The problem appears to be that the all-shared-lib target in
src/Makefile.shlib depends on $(shlib).  The first two, generic
assignments to that variable are protected like this:

ifeq ($(enable_shared), yes)
shlib       = $(NAME)$(DLSUFFIX)
endif

But the remaining, platform-specific ones are not.  So my guess is
this will work on any platform that uses the default value for shlib,
and fail on any platform that has a platform-specific override,
namely: aix, darwin, freebsd, hpux, irix, cygwin, win32.

Can you see whether the following patch fixes it for you?  It seems to
work on MacOS X, but I don't have a mingw environment handy.
